MOUNT FOR TELESCOPIC GUN SIGHTS- John H. Anderson, Burris, Wyo.

Application January 27, 1950, Serial No. 140,860

1 Claim. (Cl. 33-50) This invention relates to telescopic gun sight mounting devices, and more particularly to a telescopic sight mounting which may be quickly and easily attached and which may be removed from a gun without the use of tools.

A main object of the invention is to provide a novel and improved telescopic gun sight mount wherein the telescope may be instantly removed to allow the use of the normal iron sights for close range shooting in an emergency.

A further object of the invention is to provide an improved telescopic gun sight mount Wherein the telescope may be instantly removed for reloading the rifle with cartridge clips, as in the case of all military rifles.

A still further object of the invention is to pro vide an improved mount for a telescopic gun sight wherein spring means is utilized to hold the telescope in true alignment, at the same time absorbing shocks, impacts and vibrations, whereby the telescope retains its alignment and is protected against injury.

the gun without the use of tools and with only jl simple, manual operations.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure 1 is a side elevational view of a portion of a rifle, showing the telescopic sight mounted thereon by the use of the improved mount structure of the present invention;

Figure 2 is a view similar to Figure 1, but showing the telescopic sight removed from its mount;

Figure 3 is an enlarged, cross-sectional, detail view taken on line 3-3 of Figure 1;

Figure 4 is a cross-sectional, detail view taken on line 4-4 of Figure 3;

Figure 5 is an enlarged, cross-sectional, detail view taken on line 5-5 of Figure 1;

Figure 6 is a cross-sectional view taken on line 5-6 of Figure 5;

Figure 7 is an enlarged, perspective, detail view of the rear mount element employed in Figure 1;

Figure 8 is a fragmentary, longitudinal, crosssectional view showing a modified form of front mount element and bracket engaged therewith in accordance with the present invention;

Figure 9 is a cross-sectional view taken on line 9-9 of Figure 8;

Figure 10 is a perspective view showing the front mount element employed in Figure 8.

Referring to the drawings, there is shown a portion of a rifle having a barrel I0, a receiver II and a stock I2. The gun is equipped with a telescopic sight of any desired or conventional construction mounted in the telescope tube'|3.,

Designated at I4 is the rear sight, said rear sight being formed with a flange I5 which is fastened to the barrel I0 by suitable screws I6. The rear sight is formed with the usual V-notchl'l defining the upstanding. fingers I8, I8. Each finger I8 is formed with a forwardly opening tapered recess I9. Clamped to the forward portion of the telescope tube I3 is a ring member 20 formed with depending lugs 2|, 2|. The lugs 2| carry respective rearwardly facing tapered studs 22 adapted to be received in the recesses, I9 of the rear sight I4, as shown in Figure 4.

Designated at 23 is a channel-shaped bracket member having a bottom wall 24, upstanding side walls 25, 25, and a low transverse, forward wall 26. Bracket member 23 is secured to the receiver II by suitable screws 21 which pass through bottom wall 24. Clamped to the rearportion of the telescope tube I3 is a ring member 28 formed with a depending, transversely extending block element 29. Block element 29 is formed at its rear portion with a horizontal bore 30, said bore being provided at its ends with annular, inwardly projecting lips 3|. Positioned in the bore 30 are respective balls 32, 32 biased apart by a coiled spring 33 which urges the balls 32 against the lips 3|, whereby said balls project outwardly beyond the planes of the end surfaces of the block element. The side walls 25, 25 of the bracket member 23 are formed at their rear portions with circular apertures 35, 35 in which the balls 32, 32 are lockingly receivable when the telescope tube is mounted on the rifle, as in Figure 1.

In mounting the telescope tube on the rifle, the tapered studs 22 are first engaged in the recesses I9, I9 and the rear portion of the tube is then rotated downwardly, whereby the block element 29 enters the bracket 23 and the balls 32, 32 snap into the apertures 35. 35; The up per marginal portions of the bracket side walls 25 are flared outwardly, as shown at 36, 36, to facilitate the entry of the block element 29 into the bracket. When thus mounted, the telescope tube I3 is held firmly in its correct position.

To remove the telescopic sight, the rear portion of tube I3 is manually elevated, forcing the balls 32, 32 inwardly and disengaging said balls from the apertures 35, 35. When the block element 29 has been lifted clear of the bracket 23, the tube I3 is moved forwardly, disengaging the studs 22 from the recesses I9.

From the above description it will be apparent that the telescope tube may be mounted on or dismounted from the rifle very rapidly and by very simple, manual operations, wherein no tools are required.

Referring now to Figures 8 to 10, a modified form of front mounting structure for the telescope tube is disclosed. In the modified form of the invention, a ring 3'1 is clamped to the forwardportion of the telescope tube 13, said ring being formed with a transversely. extending block element 38 which is formed at itsforward portion with the bore 30 containing the balls 32, 32 biased apart by a coiled spring 33". The balls are retained in the bore. by suitable lips provided at the ends of the bore which allow the balls to project outwardly. Designated at 23 is a channeled bracket member secured to the barrel [0, the forward wall .26 being formed with a V-notch 39, serving as a rear sight when the telescope tube is removed. Circular apertures 35, 35 are formed in the forward portions of the side walls of the bracket member which lockingly receive the balls 32,

'32 when the block element 38 is inserted in the bracket member. The inside surfaces of the walls of the bracket member are formed with shallow, longitudinal grooves d extending from the rear ends of said walls to the apertures 35 serving to guide the balls 32- into the apertures.

I-n mounting the telescope tube, the block element 38 is slipped longitudinally into the bracket member 25 with the balls 32', 32' received in the grooves 40, the tube being moved forwardly until the balls 32', 32' snap into the apertures 35 35. The rear portion of the telescope tube is then rotated downwardly, causing the rear block element 29 to enter the rear bracket 23, and causing the locking balls 32, 32 to snap into the apertures 35, 35 of said rear bracket.

The telescope tube is dismounted by reversing the above procedure. The rear portion of the telescope tube is lifted, disengaging block element 29 from bracket 23, and the tube is then moved rearwardly, disengaging the block element 38 from the bracket member 23'.

While certain specific embodiments of im proved telescopic sight mounting devices for a gun have been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claim.

What is claimed is:

A mounting for a telescopic sight for a rifle comprising a forward support element adapted to be secured to the rifle, said support element being formed with a plurality of forwardly facing recesses, a first ring element adapted to be secured tothe telescope tube of the sight, said first ring element being provided with a depending member carrying rearwardly directed studs engageable in said recesses, a rear support element adapted to be secured to the rifle, said rear support element being generally channel shaped, being open at its rear end, having a relatively low transverse forward wall and having parallel upstanding longitudinal walls, each formed with an aperture, a second ring element adapted to be secured to therear portion of the telescope tube, said second ring element being provided with a. depending member receivable between said longitudinal walls, said latter depending member being formed with'a transverse bore, a pair of balls movably mounted in said bore, spring means urging theballs outwardly, and retaining lips at the ends of the bore limiting outward movement of the balls, the apertures in the longitudinal walls being located opposite each other and being arranged to lockingly receive said balls.
